编译配方数组键和值

我有一系列食谱。每个食谱都包含一系列成分：

[Waffle] => Array
        (
            [0] => stdClass Object
                (
                    [amount] =>  1
                    [measurement] => large
                    [ingredient] => egg 
                    [grocery] => dairy
                )
            [1] => stdClass Object
                (
                    [amount] =>  1
                    [measurement] => cup
                    [ingredient] => milk 
                    [grocery] => dairy
                )
        )
[Pancake] => Array
        (
            [0] => stdClass Object
                    (
                        [amount] =>  1
                        [measurement] => large
                        [ingredient] => egg
                        [grocery] => dairy
                    )
            [1] => stdClass Object
                (
                    [amount] =>  1
                    [measurement] => tablespoon
                    [ingredient] => maple syrup
                    [grocery] => pantry
                )
        )

我想创建一个包含所有成分的杂货清单，按成分和测量来编制数量，并根据杂货店过道进行排序。

因此，鉴于上述内容，它将输出如下内容：

DAIRY
2 large eggs
1 cup milk
PANTRY
1 tablespoon maple syrup

您可以为编写函数提供任何帮助，我们将不胜感激。
